dc.description.abstractThe availability of iron (Fe) varies considerably among diet items, as well as ecosystems. Availability of Fe has also changed due to anthropogenic environmental changes in oceanic as well as inland ecosystems. We know little about its role in the nutrition of ecologically important consumers, particularly in inland ecosystems. Physiological studies in several taxa indicate marked effects of dietary Fe on oogenesis. We predicted that differential Fe supply to algae will impact algal Fe concentration with consequences on the life history of the freshwater grazer, Daphnia magna. We found that algal Fe concentration increased with Fe supply, but did not affect algal growth, indicating that the majority of experimental Fe additions were likely adsorbed to, or stored in algal cells. Regardless, data indicate that algal Fe impacted the reproductive traits (age and size at maturity) but not juvenile growth rate of Daphnia. A subsequent experiment revealed that Fe concentration in eggs was significantly higher than the rest of Daphnia. These results indicate that the concentration of Fe in or on algal cells may vary considerably among ecosystems overlying distinct geological formations differing in Fe, possibly with important implications for zooplankton life histories. Understanding the mechanisms underlying this response is unlikely to be accomplished by a strict focus on Fe because we found correlated shifts in the algal ionome, with concomitant ionome-wide adjustments in Daphnia. Information on ionome-wide responses may be useful in better understanding the responses of biota to changes in the supply of any one element.en
